Need an EA to close my trade when opposite colored candle appears

Hey there;

I have been looking for an EA to exit my open trade when opposite colored candlestick formed.

- If minimum candlestick body size can be adjusted it would be nice.
- It should exit the trade after opposite colored candle closed.
- I need it to work on only the chart I place
- And I need it to work only at the timeframe that I place.

I made search quite some time and couldn't find such indicator. Also tried to build it but honestly could not manage to do it. Hope someone has it or write it for me. Thank you.
